As expectations for the Seattle Mariners at the big league level remain low entering 2020, what keeps most fans optimistic is the potential in the farm system. The club has some of the most prized prospects in baseball.

A recent breakdown by one of the sport’s most reputable resources is further confirmation.

The FanGraphs’ list was put together with consideration of past statistics, industry sources and in-person analysis. The scouting summaries include the prospects’ ages, the highest level of baseball they’ve reached to this point, when they’re expected to reach the MLB and their ‘Future Value’ grades -- the player’s projected range of possible outcomes in the big leagues.

White is on Seattle’s 40-man roster for spring training, while Rodriguez, Kelenic and Gilbert -- the team’s top three prospects, respectively, per MLB Pipeline -- are non-roster additions.

White, 23, is seen as the Mariners’ first baseman of the future. He’s expected to be the Opening Day starter in 2020. He hit .293 for 18 home runs, 2 triples, 13 doubles and 55 RBIs in 92 appearances for Double-A Arkansas. White signed a six-year, $24 million with Seattle in November.

Rodriguez, 19, is the top prospect in the Mariners’ system. He reached High-A Modesto last season and could reach Double-A Arkansas in 2020. Kelenic, 20, may debut in The Show by the end of the upcoming season. The Wisconsin native jumped from Class-A West Virginia to Arkansas by the end of 2019.

Gilbert, 22, reached Double-A last year and is projected to debut in the bigs in 2021.
